To all whom it may concern:

There is a shaking-bar fitted in the back of the fire-box or grate, having a projecting holder on it for each of the grates, there being a nipple cast on the flange or rim of each of the grates which the holder clasps, so that all the grates can be shaken or dumped at the same time.
